Don't Pause: Streaming Video-Language Synchrony for Online Video Understanding

arXiv:2606.06991v1 Announce Type: cross Abstract: Online Video Large Language Models (Video-LLMs) have advanced toward seamless human-AI interaction through frame-by-frame processing and proactive responding. However, a critical challenge remains in streaming scenarios: existing models typically pause video perception while generating responses, breaking real-time video-language synchrony and causing stutters. To address this, we introduce a novel paradigm for online video understanding: Streaming Video-Language Synchrony (SVLS), and present LyraV, a live streaming assistant built upon a hiera

Why this matters
Why now

The rapid advancement of Video-LLMs and the increasing demand for real-time human-AI interaction in streaming applications are driving the need for continuous perception and response.

Why it’s important

This development addresses a critical limitation in current online video understanding, moving towards seamless and synchronous multimodal AI interaction, which is essential for agentic systems.

What changes

Existing Video-LLMs will no longer need to pause video perception during response generation, enabling truly real-time, uninterrupted video-language synchrony.
